Abstract

Selon l'invention, des trains de bits de données vidéo peuvent contenir des paramètres de conformité de train de bits, tels que des paramètres de décodeur de référence hypothétique (HRD), qui peuvent être utilisés pour permettre à un décodeur de tester la conformité d'un train de bits reçu. Dans des codecs multicouches transmis à l'aide de partitions, les données vidéo peuvent être associées à un ou plusieurs ensembles de couches. Chaque ensemble de couches peut être associé à un ou plusieurs ensembles de couches de sortie. Chaque ensemble de couches de sortie peut être en outre associé à une ou plusieurs techniques de partitionnement. Des paramètres de conformité sont mappés à des partitions d'une technique de partitionnement, sur la base de l'ensemble de couches de sortie auquel la technique de partitionnement est associée. Ceci permet à une partition d'être associée à différents paramètres de conformité, en fonction de l'ensemble de couches de sortie qui est utilisé.
